A Bézier curve is a parametric curve frequently used in computer graphics and related fields. Generalizations of Bézier curves to higher dimensions are called Bézier surfaces, of which the Bézier triangle is a special case.

I wrote a small library to draw signatures in HTML apps which uses Bézier curves with variable width (based on drawing speed) to simulate hand writing effect: http://szimek.github.io/signature_pad.

I am trying to draw a curve between two points in such a way that it looks something like a hand drawn curve. How do I do this? My preliminary thinking is to (a) come up with a set of at least another ...

I am relatively new to c# and i am trying to draw the quadratic curve with an X and Y graph to scale with. The i drew curve although appears at the upper left corner of the screen which is very small ...

i have to draw a GUI in xcode cocoa app, for a parametric equalizer which i have gains, freq, and q paramiters.
My idea is to use NSBezierPath but i have no ideas how to get the points to build it.
...

I'm trying to calculate a Bezier-like spline curve that passes through a sequence of x-y coordinates. An example would be like the following output from the cscvn function in Matlab (example link):
...

I am looking for a method to modify a procedural mesh along a curve. (http://docs.unity3d.com/ScriptReference/Mesh.html) by creating reference Vector3 points along this curve and subsequently updating ...

I'm working on an SVG graphics program where the user can draw a Bézier curve and then define its length with text. By default, when the user defines its new length, I want the endpoints to stay in ...

Good day. I am using a Quadratic Bezier Curve with the following configurations:
Start Point P1 = (1, 2)
Anchor Point P2 = (1, 8)
End Point P3 = (10, 8)
I know that given a t, I know I can solve for ...

The only equation to calculate this that I can find involves t in the range [0, 1], but I have no idea how long it will take to travel the entire path, so I can't calculate (1 - t).
I know the speed ...

I am trying to reproduce the degree-3 or degree-4 3D curves typically found in parametric cad programs like Rhino or Autocad, which take any number of 3D points to create long curves. I've found that ...

Ok, so basically my problem is shifting frame of mind from solving math problems „on the paper“ to solving them by programing. Let me explain: I want to know is it possible to perform operations on ...

I am trying to draw an arc using bezier curves. I have learned that you can't draw a perfect circle using bezier curves but you can come close. Unfortunately the math is too complicated and I can't ...

I am trying to create a bezier curve using JavaScript on a HTML5 canvas. Below is the code that I have written us in the drawbeziercurve function. The result is that, I only get the four points, but ...

I need to get path of some vector shape which is transformed into Bezier curves. I have a 512x512 px canvas with 350x350 px letter "R" in the middle. I need to export somehow a coordinates of points ...

I have been trying to find a way to draw a curved line/cubic bezier line using a custom function. However, all the examples and such found on the internet, differ a little from each other and usually ...

I have the start and end points and the values of the slope of the curve at those points.
Now I have to draw a "smooth 2D bezier curve" through the two given points.
Now how to locate the two control ...

OK, so I have an application that uses variable width curves that are attached to nodes, and I got it working just fine with one control point. I am generating the control point myself, depending of ...

I want to split a bezier curve into two. For example, if there is a bezier curve between points (100,100) and (200, 100) with control points (150,150) and (175, 150), the curve should be colored in ...

We have a compass in our app and for the needle we are using an image. Which appears very pixellated...
It is possible to use a bezier line for the needle instead of a image?
If so how can i get it ...

I am trying to find an algorithm to calculate the bounding box of a given cubic bezier curve. The curve is in 3D space.
Is there a mathematic way to do this except of sampling points on the curve and ...

I'm trying to fill a face I drew in canvas (made of quadratic and bezier curves) with green. After the first bezier curve, I use a moveTo and have it direct to the endpoint of the curve (yes, a bit ...

I have a list of cubic bezier curves in 3D, such that the curves are connected to each other and closes a cycle.
I am looking for a way to create a surface from the bezier curves. Eventually i want ...

In cocos-2dx I can schedule a path with given control points in a given time using ccBezierConfig, but i want to schedule a group of paths as we did in iOS using UIBezeirPath by adding group of paths.
